Sulfur Hexafluoride (SF6): The Most Potent Greenhouse Gas
Sulfur hexafluoride (SF6) is the most potent greenhouse gas currently known, with a global warming potential (GWP) 23,500 times greater* than carbon dioxide (CO2) over a 100-year period. Though it exists in extremely small concentrations (about 35 parts per trillion), its massive heat-trapping ability and long atmospheric lifetime of 3,200 years make it a serious…
